European Telecommunication Information
(for products fitted with EU-approved modems)
Marking by the symbol indicates compliance of this equipment
to the Radio and Telecom Terminal Equipment Directive 1999/5/
EC. Such marking is indicative that this equipment meets or
exceeds the following technical standards:
CTR 21 - Attachment requirements for pan-European approval for
connection to the analogue Public Switched Telephone Networks
(PSTNs) of TE (excluding TE supporting voice telephony services) in
which network addressing, if provided, is by means of Dual Tone
Multi-Frequency (DTMF) signaling.
Although this equipment can use either loop disconnect
(pulse) or DTMF (tone) signaling, only the performance of
the DTMF signaling is subject to regulatory requirements for
correct operation.
It is therefore strongly recommended that the equipment
is set to use DTMF signaling for access to public or private
emergency services. DTMF signaling also provides faster call
setup.
This equipment has been approved to Council Decision 98/482/
EEC - “CTR 21” for Pan-European single terminal connection to the
Public Switched Telephone Network (PSTN).
However, due to differences between the individual PSTNs
provided in different countries, the approval does not, of itself,
give an unconditional assurance of successful operation on every
PSTN termination point. In the event of problems, you should
contact manufacturer Technical Support.
